Specification of Letters Patent.

Patented Feb. 23, 1915.

Application filed February 12, 1913. Serial No. 748,010.

To all whom it may concern Be it known that I, MORRIS SoHonNrnLD, acitizen of the United States, residing in Rorschach, Canton of St. Gall,Switzerland, have invented new and useful Improvements inEmbroidery-Frames, of which the following is a full, clear, and exactspecification.

The object of the present invention is an embroidery frame which isdistinguished from the embroidery frames hitherto in use, by the featurethat it is composed of two distinct groups of frame members or rods, theframe members or rods of one group being placed upright so as toconstitute the lateral parts of the frame and arranged so as to be onlymovable in a vertical direction relatively to stationary machine frameparts, While the frame members or rods of the other group carrying thefabric constitute the upper and lower parts of the frame and are guidedby the members or rods of the first group so as to be movable relativelyto them in a horizontal direction.

In the accompanying drawing, some constructional examples of theinvention are illustrated as follows:

Figure 1 shows a partial front elevation, with certain parts in section,and Fig 2 a vertical section of a preferred construction in which theembroidery frame is supported adjustable transversely 'to its stitchmotions, that is to say, transversely to the fabric plane ;v in Fig. 1,some parts have been omitted for the sake of clearness. Fig. 3 shows amodification in which the frame is rigidly mounted on the .machineframe. Figs. 4 and 5 show a guide for the frame rods of the one group.Fig. 6 shows in plan view a detail of the mechanism shown in Fig. 1.

Around fixed pivots 1 (Fig. 1) there move supporting bolts 4 which areconnected one with another by compulsorily operated elements 2, 3. Theembroidery frame is held in a position of equilibrium upon rollers 5which are placed revolubly and adjustably in the axial direction uponthe pivots 4 (Fig. 6), in consequence of the action of a counterweight6, which, by means of a bar 7 and a lever 8, is guided to move parallelwith itself. The rollers 5 are correspondingly supported in suitabletracks 9; these roller tracks 9 are provided with shoulders in front andbehind (Fig. 2) in such a manner that they carry the rollers 5 with themalong the pivots 4 when a pushing away of the frame from the fabricplane or an approach thereto is effected. These roller tracks 9 are eachrigidly connected with a vertical frame rod 12 guided vertically in theguides 10 and 11, and on the other hand, they serve for the guidance ofa lower horizontal frame rod 13 in the horizontal direction, and also anupper horizontal frame rod 14 is guided in sockets 15 of the verticalframe rods 12 in the horizontal direction. The horizontal frame rods 13,14 which form the one group of frame rods consequently participate inthe vertical motions of the vertical frame rods 12 forming the othergroup, but they can also be moved relatively to these latter in thehorizontal direction. The up-and-down motion of the embroidery frame,that is of the two groups of frame rods, is effected by means of thebolts 4, by the turning of the wheels 2,

while the horizontal relative displacement of the frame rods 13, 14 iseffected by the displacement of one of them and by a parallelogram leverconnection 16, 17 18 which turns upon the stationary axles 19 and ismade compulsory or positive for both horizontal frame rods in likemanner. The vertical rods 20 which are rigidly connected with thehorizontal frame rods 13 and 14 are. for strengthenin purposes.

The parts 21, 22, 23, 24 Fig. 2) are well known parts of the shuttlemechanism (shuttle tracks, shuttle driver bar, shuttle drivers, shuttleboard). In the construction shown in Fig. 2 the guides 10, 11 of theframe rods 12 are attached to the shuttle boards 24. These latter aresupported by the plungers 25, which are adjustable in bearings 26 on themachine frame 27, so that the entire embroidery frame is transported onthe moving-out or forward or backward adjustment of the shuttle tracksupon the parts 25.

The embroidery frame 12, 13, 14, 20 is provided as shown in Fig. 2 withfabric rollers 28, 29, 30, 31 movably supported in the well known manneron the frame parts 13, 14, 20, so as to allow of the displacement of theframe transversely to the fabric plane, but it might also be providedonly with stretching devices for the fabric of the well known kind ifthe fabric rollers were placed outside the fabric frame.

According to Fig. 3 the vertical frame rods 12 are guided in fixedbearings 32 on the cross bars 27 in a vertical direction. Moreover, thevertical frame rods 12 are so bent over above and below, that a movingout of the shuttle mechanism is possible without a transverse movementof the fabric frame. The guiding of the vertical frame rods 12 iseffected as shown in Figs. 4 and 5 by means of movable rollers 33 insuch a manner that a displacement can only take place in the axialdirection, while any turning motion of the frame rods 12 aboutthemselves is prevented by means of a longitudinal rib 3% on the framerods 12. The number of the driving points for the vertical andhorizontal frame parts or rods is here of no importance.

Obviously the arrangement illustrated in the drawing according to whichthe weight of the frame rests upon the pivots 1 placed below the frameis only shown by way of example.

l/Vhat I claim is:

1. In an embroidering machine, a stationary machine frame, a fabricframe composed of two separate groups of frame rods, one of which hasits frame rods distributed in upright position from distance to distanceover the length of the frame so as to constitute side and intermediateframe parts and arranged so as to be only movable in a verticaldirection relatively to the machine frame, while the frame rods of theother group carrying the fabric constitute the upper and lowerlongitudinal parts of the frame and are independently guided by andcoupled to the frame rods of the first group so as to be movablerelatively to them in one and the same horizontal direction.

2. In an embroidering machine, a stationary machine frame, a fabricframe composed of two distinct groups of frame rods, constituting theupper, lower and lateral parts of the frame, the frame rods of one groupbeing placed upright so as to constitute the lateral parts of the frameand arranged so as to be only movable in a vertical direction relativelyto the machine frame, while the frame rods of the other group constitutethe upper and lower parts of the frame, extending over the whole lengththereof, and are movably carried by the frame rods of the first group soas to be displaceable relatively to them in a horizontal direction,positive guide rollers being provided for the upright frame rods of thefirst group.

3. In an embroidering machine, a stationary machine frame, a fabricframecomposed of two distinct groups of frame rods constituting theupper, lower and lateral parts of the frame, the frame rods of one groupbeing placed upright so as to constitute the lateral parts of the frameand arranged so as to be movable in a vertical direction relatively tothe machine frame, while the frame rods of the other group constitutethe upper and lower parts of the frame and are movably carried by theframe rods of the first group so as to be displaceable relatively tothem in a horizontal direction, adjustable guide means being providedfor the upright frame rods of the first group.

4:. In an embroidering machine, a machine frame carrying a shuttleboard, a fabric frame comprising two distinct groups of members, theframe members of one group being placed upright and movable in theGoples of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents,
